​

Answer 1

19.2 grams

Explanation:

Assuming it is a straight proportion, then the givens are

w1 = 150 pounds

m1 = 24 grams

w2 = 120 pounds

m2 = x

m = medication amount.

w = weight

Equation

m1/w1 = m2/w2

Solution

24/150 = x / 120 Multiply both sides by 120

24 * 120/150 = x 120 /120

2880/150 = x Do the division

19.2 grams = x The amount the 120 pound woman should receive.
